In my leisure time I'm keen diy hobbiest. I can contribute to the forum by my experience with home-made HRV/air conditioning/CO2 control system based on PIC18F2550 and PicBasicPRO connected to RaspberryPI via serial linux terminal. Raspberry PI synchronizes PIC date and time and collects measured data from PIC and stores them to USB stick.I would be happy if I could contribute also by my professional experience related to Process PID controls, Electric Drives controls, ABB Advant controllers, ABB 800xA/AC800M, cold rolling mill, paper mill, boiler combustion and DRI controls.
